Welcome to my Chain of ResponsibilityDesign Pattern Tutorial! Wow, that was a mouthful!
This pattern has a group of objects that are expected to between them be able to solve a problem. If the first Object can't solve it, it passes the data to the next Object in the chain. In this tutorial, I'll use it to make the right calculations based off of a String request. While that is pretty simple the capabilities of this pattern are endless.

"Opening an exciting new Era of Cryptofinance for the Internet of Values"
FUSION is a public blockchain devoting itself to creating an inclusive cryptofinancial platform by providing cross-chain, cross-organization, and cross-datasource smart contracts.
The FUSION inclusive cryptofinance platform is a public blockchain. The FUSION Foundation, as a sponsor of the project, is working for the promising ecosystem of the blockchain rather than corporate profits as traditional enterprise projects do. The FUSION platform, which benefits all token holders, does not belong to any single organization or individual and is a platform embracing the entire blockchain token community.
Sound familiar? It should. The vision sounds a lot like WanChain. With a strong, experienced team, they have what it takes to compete.

Video tutorial/guide showing how to start mining Bitcoins from home super simple and easily, for beginners, or advanced users, using NiceHash in 2017. Bitcoins are a cryptocurrency, like Litecoins and Ethereum which offer an anonymous form of digital currency. This video will show you how to setup a bitcoin wallet, download and install the mining program (nicehash), link it up to your wallet using the bitcoin address, and use the optimal algorithm for mining the most bitcoins and earning the money. Mining these Bitcoins is a way to introduce new bitcoins into the world, as well as verify transactions occurring in the blockchain. You can earn bitcoins and money, by mining at home from your very own PC computer. I also include some tips which helped me mine!
Nicehash recently suffered a very complex hack which affected Miners and users of the Nicehash wallet. This attack took them down, offline, for about 2 weeks, but they are currently back up and back at it once more--LIVE AGAIN! They have ensured a huge increase in security, as well as getting people's money back before January 31st, 2018.

You will get paid less frequently with external wallets like Coinbase, so if you want quicker payments, you should open a NiceHash wallet.
You should mine with a powerful Graphics Card (GPU), and only on desktop computers (Not laptops). You need a bitcoin wallet like Coinbase, and you will need NiceHash. Make sure to benchmark your algorithms to get the most amount of bitcoins.
Bitcoin mining is the process of adding transaction records to Bitcoin's public ledger of past transactions or blockchain. This ledger of past transactions is called the block chain as it is a chain of blocks. The block chain serves to confirm transactions to the rest of the network as having taken place. Bitcoin nodes use the block chain to distinguish legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere.
URGENT || PLEASE READ BEFORE COMMENTING:

3) PLEASE DO NOT ask me if your computer is good enough for mining. I get dozens of comments a day asking essentially the same thing, so I am leaving the answer here for all of you guys: -Anything Before a GTX 9 Series: Don't mine! -GTX 9 Series: Fully capable of mining, but not recommend because it is not very efficient. -GTX 1050/1050TI: Full capable of mining with high efficiency, but not very powerful. Don't expect too much out of it. -GTX 1060 or better: What I recommend for mining. Powerful enough to see true return with high efficiency.
--------------
4) If you have a laptop, you most likely SHOULD NOT mine. The only exception is if you have a laptop with a GTX 1060 or higher, and you did a test run for an hour with all of your thermals under 80 degrees. Even then...it's not recommended.

Chain

A chain is a series of connected links which are typically made of metal. A chain may consist of two or more links.

Those designed for lifting, such as when used with a hoist; for pulling; or for securing, such as with a bicycle lock, have links that are torus shaped, which make the chain flexible in two dimensions (The fixed third dimension being a chain's length.)

Those designed for transferring power in machines have links designed to mesh with the teeth of the sprockets of the machine, and are flexible in only one dimension. They are known as roller chains, though there are also non-roller chains such as block chain.

Two distinct chains can be connected using a quick link which resembles a carabiner with a screw close rather than a latch.

Uses for chain

Uses for chain include:

Decoration

Chain of office, collar or heavy gold chain worn as insignia of office or a mark of fealty in medieval Europe and the United Kingdom

Decorating clothing, some people wear wallets with chains connected to their belts, or pants decorated with chains

Raw data, i.e. unprocessed data, is a collection of numbers, characters; data processing commonly occurs by stages, and the "processed data" from one stage may be considered the "raw data" of the next. Field data is raw data that is collected in an uncontrolled in situ environment. Experimental data is data that is generated within the context of a scientific investigation by observation and recording.

The Latin word "data" is the plural of "datum", and still may be used as a plural noun in this sense. Nowadays, though, "data" is most commonly used in the singular, as a mass noun (like "information", "sand" or "rain").

Supply chain

A supply chain is a system of organizations, people, activities, information, and resources involved in
moving a product or service from supplier to customer. Supply chain activities involve the transformation of natural resources, raw materials, and components into a finished product that is delivered to the end customer. In sophisticated supply chain systems, used products may re-enter the supply chain at any point where residual value is recyclable. Supply chains link value chains.

Overview

A typical supply chain begins with the ecological, biological, and political regulation of natural resources, followed by the human extraction of raw material, and includes several production links (e.g., component construction, assembly, and merging) before moving on to several layers of storage facilities of ever-decreasing size and increasingly remote geographical locations, and finally reaching the consumer.

Bitcoins are created as a reward for payment processing work in which users offer their computing power to verify and record payments into a public ledger. This activity is called mining and miners are rewarded with transaction fees and newly created bitcoins. Besides being obtained by mining, bitcoins can be exchanged for other currencies, products, and services. Users can send and receive bitcoins for an optional transaction fee.

The Bitcoin and Blockchain Technology Explained

The Bitcoin and Blockchain Technology Explained

The Bitcoin and Blockchain Technology Explained

A block chain is a transaction database shared by all nodes participating in a system based on the Bitcoin protocol. A full copy of a currency's block chain contains every transaction ever executed in the currency. With this information, one can find out how much value belonged to each address at any point in history.

-------------------------------------------------------------------
Every block contains a hash of the previous block. This has the effect of creating a chain of blocks from the genesis block to the current block. Each block is guaranteed to come after the previous block chronologically because the previous block's hash would otherwise not be known. Each block is also computationally impractical to modify once it has been in the chain for a while because every block after it would also have to be regenerated. These properties are what make double-spending of bitcoins very difficult. The block chain is the main innovation of Bitcoin.
Honest generators only build onto a block (by referencing it in blocks they create) if it is the latest block in the longest valid chain. "Length" is calculated as total combined difficulty of that chain, not number of blocks, though this distinction is only important in the context of a few potential attacks. A chain is valid if all of the blocks and transactions within it are valid, and only if it starts with the genesis block.
For any block on the chain, there is only one path to the genesis block. Coming from the genesis block, however, there can be forks. One-block forks are created from time to time when two blocks are created just a few seconds apart. When that happens, generating nodes build onto whichever one of the blocks they received first. Whichever block ends up being included in the next block becomes part of the main chain because that chain is longer. More serious forks have occurred after fixing bugs that required backward-incompatible changes.
Blocks in shorter chains (or invalid chains) are not used for anything. When the bitcoin client switches to another, longer chain, all valid transactions of the blocks inside the shorter chain are re-added to the pool of queued transactions and will be included in another block. The reward for the blocks on the shorter chain will not be present in the longest chain, so they will be practically lost, which is why a network-enforced 100-block maturation time for generations exists.
These blocks on the shorter chains are often called "orphan" blocks. This is because the generation transactions do not have a parent block in the longest chain, so these generation transactions show up as orphan in the listtransactions RPC call. Several pools have misinterpreted these messages and started calling their blocks "orphans". In reality, these blocks have a parent block, and might even have children.
Because a block can only reference one previous block, it is impossible for two forked chains to merge.

Bitcoin and Ethereum miners collectively make up what is perhaps the most powerful computational resource in the world. However, mobile phones from the early 2000's could arguably run more complex operations than these networks combined. While blockchains themselves may never reach the level of computational power of modern computers, they may be leveraged as the underlying verification layer for centralized computing.
We're joined by JasonTeutsch and Christian Reitwiessner. They are the co-authors of a visionary whitepaper which describes Truebit. This protocol would allow complex computations to be executed on off-chain systems while being validated by Ethereum miners. The results of these computations would consequently be available to on-chain smart contracts. Truebit makes clever use of proof systems and game theory to build a protocol where a Task Giver can ask a third party, the Solver, to execute a complex computation in exchange for a reward. Not limited to Solidity, these could be executed in traditional languages such as Go, Python or C++. Verifiers could then challenge the results, incentivising the Solver to be honest or see his reward be stripped away. This incentive structure would guarantee fast and reliable results while eliminating the need for a trusted third party.
Topics discussed in this episode:
- Jason and Christian respective backgrounds in the ecosystem.
- The core problem being addressed by Truebit
- Why a scalable decentralized computational resource is desirable
- How Truebit makes use of proof systems and game theory to enable trusted computations off-chain
- How the verification game works the incentive structures proposed in Truebit
- The various use cases for Truebit
- How Truebit could allow for blockchain interoperability without the need for ""blockchain of blockchains"" type networks

The protocol of FUSION provides APIs to encompass various blockchain tokens, sources of data and different off-chain values into one public chain. As a result, it will enable blockchain communities, centralized organizations and individuals help each other.
Likewise, a number of tokens can be mapped onto the ICO. That's achieved by means of distributed management of control rights. It enables both multi-token smart contracts and division of ownership possible.

The Bitcoin and Blockchain Technology Explained

A block chain is a transaction database shared by all nodes participating in a system based on the Bitcoin protocol. A full copy of a currency's block chain contains every transaction ever executed in the currency. With this information, one can find out how much value belonged to each address at any point in history.

What motivated the concept of Markov chains & Markov models? FeaturingPlato's theory of forms, Jacob Bernoulli's weak law of large numbers and Central Limit Theorem. This leads to to Andrey Markov's idea that dependent random events also converge on average distributions.

Video tutorial/guide showing how to start mining Bitcoins from home super simple and easily, for beginners, or advanced users, using NiceHash in 2017. Bitcoins are a cryptocurrency, like Litecoins and Ethereum which offer an anonymous form of digital currency. This video will show you how to setup a bitcoin wallet, download and install the mining program (nicehash), link it up to your wallet using the bitcoin address, and use the optimal algorithm for mining the most bitcoins and earning the money. Mining these Bitcoins is a way to introduce new bitcoins into the world, as well as verify transactions occurring in the blockchain. You can earn bitcoins and money, by mining at home from your very own PC computer. I also include some tips which helped me mine!
Nicehash recently suffered a very complex hack which affected Miners and users of the Nicehash wallet. This attack took them down, offline, for about 2 weeks, but they are currently back up and back at it once more--LIVE AGAIN! They have ensured a huge increase in security, as well as getting people's money back before January 31st, 2018.

You will get paid less frequently with external wallets like Coinbase, so if you want quicker payments, you should open a NiceHash wallet.
You should mine with a powerful Graphics Card (GPU), and only on desktop computers (Not laptops). You need a bitcoin wallet like Coinbase, and you will need NiceHash. Make sure to benchmark your algorithms to get the most amount of bitcoins.
Bitcoin mining is the process of adding transaction records to Bitcoin's public ledger of past transactions or blockchain. This ledger of past transactions is called the block chain as it is a chain of blocks. The block chain serves to confirm transactions to the rest of the network as having taken place. Bitcoin nodes use the block chain to distinguish legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere.
URGENT || PLEASE READ BEFORE COMMENTING:
1) Nicehash has changed they send payments. Link here: https://www.nicehash.com/help/when-and-how-do-you-get-paid You will get paid less frequently with external wallets like Coinbase! So use their wallet if you want quicker payouts.

3) PLEASE DO NOT ask me if your computer is good enough for mining. I get dozens of comments a day asking essentially the same thing, so I am leaving the answer here for all of you guys: -Anything Before a GTX 9 Series: Don't mine! -GTX 9 Series: Fully capable of mining, but not recommend because it is not very efficient. -GTX 1050/1050TI: Full capable of mining with high efficiency, but not very powerful. Don't expect too much out of it. -GTX 1060 or better: What I recommend for mining. Powerful enough to see true return with high efficiency.
--------------
4) If you have a laptop, you most likely SHOULD NOT mine. The only exception is if you have a laptop with a GTX 1060 or higher, and you did a test run for an hour with all of your thermals under 80 degrees. Even then...it's not recommended.

A block chain is a transaction database shared by all nodes participating in a system based on the Bitcoin protocol. A full copy of a currency's block chain contains every transaction ever executed in the currency. With this information, one can find out how much value belonged to each address at any point in history.

Every block contains a hash of the previous block. This has the effect of creating a chain of blocks from the genesis block to the current block. Each block is guaranteed to come after the previous block chronologically because the previous block's hash would otherwise not be known. Each block is also computationally impractical to modify once it has been in the chain for a while because every block after it would also have to be regenerated. These properties are what make double-spending of bitcoins very difficult. The block chain is the main innovation of Bitcoin.
Honest generators only build onto a block (by referencing it in blocks they create) if it is the latest block in the longest valid chain. "Length" is calculated as total combined difficulty of that chain, not number of blocks, though this distinction is only important in the context of a few potential attacks. A chain is valid if all of the blocks and transactions within it are valid, and only if it starts with the genesis block.
For any block on the chain, there is only one path to the genesis block. Coming from the genesis block, however, there can be forks. One-block forks are created from time to time when two blocks are created just a few seconds apart. When that happens, generating nodes build onto whichever one of the blocks they received first. Whichever block ends up being included in the next block becomes part of the main chain because that chain is longer. More serious forks have occurred after fixing bugs that required backward-incompatible changes.
Blocks in shorter chains (or invalid chains) are not used for anything. When the bitcoin client switches to another, longer chain, all valid transactions of the blocks inside the shorter chain are re-added to the pool of queued transactions and will be included in another block. The reward for the blocks on the shorter chain will not be present in the longest chain, so they will be practically lost, which is why a network-enforced 100-block maturation time for generations exists.
These blocks on the shorter chains are often called "orphan" blocks. This is because the generation transactions do not have a parent block in the longest chain, so these generation transactions show up as orphan in the listtransactions RPC call. Several pools have misinterpreted these messages and started calling their blocks "orphans". In reality, these blocks have a parent block, and might even have children.
Because a block can only reference one previous block, it is impossible for two forked chains to merge.

Bitcoin and Ethereum miners collectively make up what is perhaps the most powerful computational resource in the world. However, mobile phones from the early 2000's could arguably run more complex operations than these networks combined. While blockchains themselves may never reach the level of computational power of modern computers, they may be leveraged as the underlying verification layer for centralized computing.
We're joined by JasonTeutsch and Christian Reitwiessner. They are the co-authors of a visionary whitepaper which describes Truebit. This protocol would allow complex computations to be executed on off-chain systems while being validated by Ethereum miners. The results of these computations would consequently be available to on-chain smart contracts. Truebit makes clever use of proof systems and game theory to build a protocol where a Task Giver can ask a third party, the Solver, to execute a complex computation in exchange for a reward. Not limited to Solidity, these could be executed in traditional languages such as Go, Python or C++. Verifiers could then challenge the results, incentivising the Solver to be honest or see his reward be stripped away. This incentive structure would guarantee fast and reliable results while eliminating the need for a trusted third party.
Topics discussed in this episode:
- Jason and Christian respective backgrounds in the ecosystem.
- The core problem being addressed by Truebit
- Why a scalable decentralized computational resource is desirable
- How Truebit makes use of proof systems and game theory to enable trusted computations off-chain
- How the verification game works the incentive structures proposed in Truebit
- The various use cases for Truebit
- How Truebit could allow for blockchain interoperability without the need for ""blockchain of blockchains"" type networks

The protocol of FUSION provides APIs to encompass various blockchain tokens, sources of data and different off-chain values into one public chain. As a result, it will enable blockchain communities, centralized organizations and individuals help each other.
Likewise, a number of tokens can be mapped onto the ICO. That's achieved by means of distributed management of control rights. It enables both multi-token smart contracts and division of ownership possible.

Say hello to the decentralized economy -- the blockchain is about to change everything. In this lucid explainer of the complex (and confusing) technology, Bettina Warburg describes how the blockchain will eliminate the need for centralized institutions like banks or governments to facilitate trade, evolving age-old models of commerce and finance into something far more interesting: a distributed, transparent, autonomous system for exchanging value.

Streamr stack for P2P data transport and off-chain analytics

This talk is a technical overview of the Streamr decentralized stack which makes it possible for machines and connected devices to share and monetize real-time data. The stack is built on top of Ethereum smart contracts which are used for access control, permissioning, and secure licensing payments. Data transport is implemented by a P2P network where nodes are incentivized by payments in DATAcoin, the native token of the project. The network implements scalable, robust and low-latency pub/sub messaging infrastructure for data delivery. The layer above consists of data market where data streams can be showcased and shared between producers and consumers who transact using DATAcoin.

Andreas M. Antonopoulos | What is Happening With Bitcoin? Misconceptions about Lightning Network

What are some misconceptions about the Lightning Network? How does the onion-routing work? How does channel funding work? Are there any security or legal risks to running a Lightning node? How far is the development so far in making this technology user-friendly?
This is not a choice between on-chain and off-chain. A large portion of transaction volume has already been conducted off-chain (i.e. within the private databases of exchanges) for years; what second-layer solutions like the Lightning Network do is to allow for similar low-cost activity without sacrificing most of the security model and trustless nature of Bitcoin. Decentralisation is not a Boolean value, it is a range.

Blockchain Consensus Algorithms and Artificial Intelligence

Is blockchain + AI a winning combo? Yes! They are complementary technologies, and knowing how both work will make you a much more powerful developer. Artificial Intelligence can use the power of the blockchain to audit data, add incentives to its goals, and even create new types of meritocratic organizations. In this video, i'll talk about how they can both work together, code out the proof of work algorithm in python, then talk about a few other consensus algorithms at a high level.

This episode covers
- the three kinds of command blocks: impulse, chain, and repeating
- activating impulse (orange) commands with redstone power
- toggling between 'needs redstone' and 'always active'
- chains and 'arrow order' of sequential chain (green) blocks
- conditional chain blocks for if-then
- chaining conditionals
- very basics of loops with repeat (purple) command blocks

We're joined by JasonTeutsch and Christian Reitwiessner. They are the co-authors of a visionary whitepaper which describes Truebit. This protocol would allow complex computations to be executed on off-chain systems while being validated by Ethereum miners. The results of these computations would consequently be available to on-chain smart contracts. Truebit makes clever use of proof systems and game theory to build a protocol where a Task Giver can ask a third party, the Solver, to execute a complex computation in exchange for a reward. Not limited to Solidity, these could be executed in traditional languages such as Go, Python or C++. Verifiers could then challenge the results, incentivising the Solver to be honest or see his reward be stripped away. This incentive structure would guarantee fast and reliable results while eliminating the need for a trusted third party.
Topics discussed in this episode:

- The core problem being addressed by Truebit
- Why a scalable decentralized computational resource is desirable
- How Truebit makes use of proof systems and game theory to enable trusted computations off-chain
- How the verification game works the incentive structures proposed in Truebit

The LightningNetwork is not only about payment channels, there is also routing between the payment channels of others. You do not need to open a channel with every party you want to transact with. If a merchant does open a channel, they do not have to close the channel in order to be paid.

What are some misconceptions about the Lightning Network? How does the onion-routing work? How does channel funding work? Are there any security or legal risks to running a Lightning node? How far is the development so far in making this technology user-friendly?
This is not a choice between on-chain and off-chain. A large portion of transaction volume has already been conducted off-chain (i.e. within the private databases of exchanges) for years; what second-layer solutions like the Lightning Network do is to allow for similar low-cost activity without sacrificing most of the security model and trustless nature of Bitcoin. Decentralisation is not a Boolean value, it is a range.
The LightningNetwork is not only about payment channels, there is also routing between the payment channels of others. You do not need to open a channel with every party you want to transact with. If a merchant does open a channel, they do not have to close the channel in order to be paid.

While taking a little time off on their way to Sunyshore City and Ash's next Gym Battle, our heroes discover Team Rocket's Meowth. The dazed Pokémon has been separated from Jessie and James after a rough run-in with Team Galactic! After explaining the situation, Meowth and our heroes head out to Team Galactic's secret base to rescue Jessie and James, as well as Looker from the InternationalPolice.
As Team Galactic continues to put the pieces together to accomplish its evil plans, our heroes confront the mysterious Jupiter of Team Galactic. She informs them she is aware of their previous encounters with the three lake Pokémon Mesprit, Azelf, and Uxie. This news bewilders our heroes all the more. Meanwhile, the gang (along with Meowth) rescues Looker, who has been trapped in a cell with Jessie and James. Team Galactic gets away, leaving Looker and our heroes still wondering what the evil organization is up to.
While trying to unravel the mystery, Looker discovers an object left behind by Team Galactic that, upon examination, destroys every bit of data the International Police have collected on them

Is blockchain + AI a winning combo? Yes! They are complementary technologies, and knowing how both work will make you a much more powerful developer. Artificial Intelligence can use the power of the blockchain to audit data, add incentives to its goals, and even create new types of meritocratic organizations. In this video, i'll talk about how they can both work together, code out the proof of work algorithm in python, then talk about a few other consensus algorithms at a high level.

I'll teach you Minecraft command block programming! This series will help you learn step-by-step using the 1.9 snapshots of Minecraft for PC.
This episode covers
- the three kinds of command blocks: impulse, chain, and repeating
- activating impulse (orange) commands with redstone power
- toggling between 'needs redstone' and 'always active'
- chains and 'arrow order' of sequential chain (green) blocks
- conditional chain blocks for if-then
- chaining conditionals
- very basics of loops with repeat (purple) command blocks
Teaching programming to a wide audience is a challenge. I'll try to go at a slow, detailed pace that most viewers can follow. If you know a topic well, you might want to watch at 1.5x or 2x speed to skim.
Teaching complicated subject matter is a challenge. During an episode, I sometimes do 'handwaving', or tell white lies or lies of omission, for simplicity to teach beginners. At the end of each epsiode, I'll have a segment where I try to clear up the lies I know I told, going into more gory detail.

Hey guys in this video today I talk about how to build up capital to really get a piece of the growing crypto world. Chaingroup the first website I talk about is a trusted lending site that has been going on for almost half a year and is one of the best lending platforms still around. The groups that I would personally invest in is X-bots, and Dragon foundation. One of them being up for over 150 days is a very healthy sign and to top it off, the group raised 10 million dollars putting them in a position to not even need our money but they will be paying out for 180 days after receiving your loan. Chain group is a good step to build your capital to use with trade bots. The second thing I address is the use of trade bots yourself and how you can earn your profit plus the rising of bitcoin and how it is the most effective way of earning huge profits, but you need enough capital to run things smoothly. I believe if we can build our bitcoin up enough that we can trade successfully and not have to rely on lending platforms. Reward table is still running just deposit the minimum amount for now and use your profits to keep playing. Also join my discord! Thanks for watching everyone :)

Streamr stack for P2P data transport and off-chain analytics

This talk is a technical overview of the Streamr decentralized stack which makes it possible for machines and connected devices to share and monetize real-time data. The stack is built on top of Ethereum smart contracts which are used for access control, permissioning, and secure licensing payments. Data transport is implemented by a P2P network where nodes are incentivized by payments in DATAcoin, the native token of the project. The network implements scalable, robust and low-latency pub/sub messaging infrastructure for data delivery. The layer above consists of data market where data streams can be showcased and shared between producers and consumers who transact using DATAcoin. Streamr Engine is an event processing and analytics layer capable of reacting to incoming real-time data and taking action. Finally, there is a graphical a visual programming environment where users can easily create data processing systems by connecting modules in a drag-and-drop fashion. There’s a number of interesting technical questions on how to achieve sufficient throughput and scalability and how to ensure node coordination in the P2P network.

Welcome to my Chain of ResponsibilityDesign Pattern Tutorial! Wow, that was a mouthful!
This pattern has a group of objects that are expected to between them be able to solve a problem. If the first Object can't solve it, it passes the data to the next Object in the chain. In this tutorial, I'll use it to make the right calculations based off of a String request. While that is pretty simple the capabilities of this pattern are endless.

"Opening an exciting new Era of Cryptofinance for the Internet of Values"
FUSION is a public blockchain devoting itself to creating an inclusive cryptofinancial platform by providing cross-chain, cross-organization, and cross-datasource smart contracts.
The FUSION inclusive cryptofinance platform is a public blockchain. The FUSION Foundation, as a sponsor of the project, is working for the promising ecosystem of the blockchain rather than corporate profits as traditional enterprise projects do. The FUSION platform, which benefits all token holders, does not belong to any single organization or individual and is a platform embracing the entire blockchain token community.
Sound familiar? It should. The vision sounds a lot like WanChain. With a strong, experienced team, they have what it takes to compete.

Problem:
The problem for the FUSION project to solve is: FUSION will create a public chain to use distributed nodes to control the private keys of various tokens and in this way, it will not only map various blockchain tokens to it, but will also achieve the function of cross-chain smart contracts. FUSION will also provide interfaces to communicate off-chain organizations and data sources so that it will greatly improving interoperability and scalability of the current Internet of Values and making itself an inclusive cryptofinance platform that serves the Internet of Values.
Solutions:
FUSION has a novel design that will solve interoperability (using sharding), scalability (PoW + PoS), and usability (adoption program).

What is a Markov chain?

What motivated the concept of Markov chains & Markov models? FeaturingPlato's theory of forms, Jacob Bernoulli's weak law of large numbers and Central Limit Theorem. This leads to to Andrey Markov's idea that dependent random events also converge on average distributions.

How to Mine Bitcoin COMPLETE Guide 2017/2018 (EASIEST METHOD)

Video tutorial/guide showing how to start mining Bitcoins from home super simple and easily, for beginners, or advanced users, using NiceHash in 2017. Bitcoins are a cryptocurrency, like Litecoins and Ethereum which offer an anonymous form of digital currency. This video will show you how to setup a bitcoin wallet, download and install the mining program (nicehash), link it up to your wallet using the bitcoin address, and use the optimal algorithm for mining the most bitcoins and earning the money. Mining these Bitcoins is a way to introduce new bitcoins into the world, as well as verify transactions occurring in the blockchain. You can earn bitcoins and money, by mining at home from your very own PC computer. I also include some tips which helped me mine!
Nicehash recently suffered a very complex hack which affected Miners and users of the Nicehash wallet. This attack took them down, offline, for about 2 weeks, but they are currently back up and back at it once more--LIVE AGAIN! They have ensured a huge increase in security, as well as getting people's money back before January 31st, 2018.

NOTE: Nicehash has changed the way they send payments. Link here:
https://www.nicehash.com/help/when-and-how-do-you-get-paid
You will get paid less frequently with external wallets like Coinbase, so if you want quicker payments, you should open a NiceHash wallet.
You should mine with a powerful Graphics Card (GPU), and only on desktop computers (Not laptops). You need a bitcoin wallet like Coinbase, and you will need NiceHash. Make sure to benchmark your algorithms to get the most amount of bitcoins.
Bitcoin mining is the process of adding transaction records to Bitcoin's public ledger of past transactions or blockchain. This ledger of past transactions is called the block chain as it is a chain of blocks. The block chain serves to confirm transactions to the rest of the network as having taken place. Bitcoin nodes use the block chain to distinguish legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere.
URGENT || PLEASE READ BEFORE COMMENTING:
1) Nicehash has changed they send payments. Link here: https://www.nicehash.com/help/when-and-how-do-you-get-paid You will get paid less frequently with external wallets like Coinbase! So use their wallet if you want quicker payouts.
-------------
2) Nicehash recently suffered a very complex hack which affected Miners and users of the Nicehash wallet. This attack took them down, offline, for about 2 weeks, but they are currently back up and back at it once more--LIVE AGAIN! They have ensured a huge increase in security, as well as getting people's money back before January 31st, 2018.
--------------
3) PLEASE DO NOT ask me if your computer is good enough for mining. I get dozens of comments a day asking essentially the same thing, so I am leaving the answer here for all of you guys: -Anything Before a GTX 9 Series: Don't mine! -GTX 9 Series: Fully capable of mining, but not recommend because it is not very efficient. -GTX 1050/1050TI: Full capable of mining with high efficiency, but not very powerful. Don't expect too much out of it. -GTX 1060 or better: What I recommend for mining. Powerful enough to see true return with high efficiency.
--------------
4) If you have a laptop, you most likely SHOULD NOT mine. The only exception is if you have a laptop with a GTX 1060 or higher, and you did a test run for an hour with all of your thermals under 80 degrees. Even then...it's not recommended.
--------------
5) If you have an AMD GPU, use the legacy program. I have a guide on it here: https://www.youtube.com/watch?v=IwsxgLBZu6g

The Bitcoin and Blockchain Technology Explained

A block chain is a transaction database shared by all nodes participating in a system based on the Bitcoin protocol. A full copy of a currency's block chain contains every transaction ever executed in the currency. With this information, one can find out how much value belonged to each address at any point in history.

-------------------------------------------------------------------
Every block contains a hash of the previous block. This has the effect of creating a chain of blocks from the genesis block to the current block. Each block is guaranteed to come after the previous block chronologically because the previous block's hash would otherwise not be known. Each block is also computationally impractical to modify once it has been in the chain for a while because every block after it would also have to be regenerated. These properties are what make double-spending of bitcoins very difficult. The block chain is the main innovation of Bitcoin.
Honest generators only build onto a block (by referencing it in blocks they create) if it is the latest block in the longest valid chain. "Length" is calculated as total combined difficulty of that chain, not number of blocks, though this distinction is only important in the context of a few potential attacks. A chain is valid if all of the blocks and transactions within it are valid, and only if it starts with the genesis block.
For any block on the chain, there is only one path to the genesis block. Coming from the genesis block, however, there can be forks. One-block forks are created from time to time when two blocks are created just a few seconds apart. When that happens, generating nodes build onto whichever one of the blocks they received first. Whichever block ends up being included in the next block becomes part of the main chain because that chain is longer. More serious forks have occurred after fixing bugs that required backward-incompatible changes.
Blocks in shorter chains (or invalid chains) are not used for anything. When the bitcoin client switches to another, longer chain, all valid transactions of the blocks inside the shorter chain are re-added to the pool of queued transactions and will be included in another block. The reward for the blocks on the shorter chain will not be present in the longest chain, so they will be practically lost, which is why a network-enforced 100-block maturation time for generations exists.
These blocks on the shorter chains are often called "orphan" blocks. This is because the generation transactions do not have a parent block in the longest chain, so these generation transactions show up as orphan in the listtransactions RPC call. Several pools have misinterpreted these messages and started calling their blocks "orphans". In reality, these blocks have a parent block, and might even have children.
Because a block can only reference one previous block, it is impossible for two forked chains to merge.

Bitcoin and Ethereum miners collectively make up what is perhaps the most powerful computational resource in the world. However, mobile phones from the early 2000's could arguably run more complex operations than these networks combined. While blockchains themselves may never reach the level of computational power of modern computers, they may be leveraged as the underlying verification layer for centralized computing.
We're joined by JasonTeutsch and Christian Reitwiessner. They are the co-authors of a visionary whitepaper which describes Truebit. This protocol would allow complex computations to be executed on off-chain systems while being validated by Ethereum miners. The results of these computations would consequently be available to on-chain smart contracts. Truebit makes clever use of proof systems and game theory to build a protocol where a Task Giver can ask a third party, the Solver, to execute a complex computation in exchange for a reward. Not limited to Solidity, these could be executed in traditional languages such as Go, Python or C++. Verifiers could then challenge the results, incentivising the Solver to be honest or see his reward be stripped away. This incentive structure would guarantee fast and reliable results while eliminating the need for a trusted third party.
Topics discussed in this episode:
- Jason and Christian respective backgrounds in the ecosystem.
- The core problem being addressed by Truebit
- Why a scalable decentralized computational resource is desirable
- How Truebit makes use of proof systems and game theory to enable trusted computations off-chain
- How the verification game works the incentive structures proposed in Truebit
- The various use cases for Truebit

Streamr stack for P2P data transport and off-chain analytics

This talk is a technical overview of the Streamr decentralized stack which makes it possible for machines and connected devices to share and monetize real-time data. The stack is built on top of Ethereum smart contracts which are used for access control, permissioning, and secure licensing payments. Data transport is implemented by a P2P network where nodes are incentivized by payments in DATAcoin, the native token of the project. The network implements scalable, robust and low-latency pub/sub messaging infrastructure for data delivery. The layer above consists of data market where data streams can be showcased and shared between producers and consumers who transact using DATAcoin. Streamr Engine is an event processing and analytics layer capable of reacting to incoming real-time data and taking action. Finally, there is a graphical a visual programming environment where users can easily create data processing systems by connecting modules in a drag-and-drop fashion. There’s a number of interesting technical questions on how to achieve sufficient throughput and scalability and how to ensure node coordination in the P2P network.

Andreas M. Antonopoulos | What is Happening With Bitcoin? Misconceptions about Lightning Network

What are some misconceptions about the Lightning Network? How does the onion-routing work? How does channel funding work? Are there any security or legal risks to running a Lightning node? How far is the development so far in making this technology user-friendly?
This is not a choice between on-chain and off-chain. A large portion of transaction volume has already been conducted off-chain (i.e. within the private databases of exchanges) for years; what second-layer solutions like the Lightning Network do is to allow for similar low-cost activity without sacrificing most of the security model and trustless nature of Bitcoin. Decentralisation is not a Boolean value, it is a range.
The LightningNetwork is not only about payment channels, there is also routing between the payment channels of others. You do not need to open a channel with every party you want to transact with. If a merchant does open a channel, they do not have to close the channel in order to be paid.

Pokemon Episode 619 – Unlocking the Red Chain of Events!

While taking a little time off on their way to Sunyshore City and Ash's next Gym Battle, our heroes discover Team Rocket's Meowth. The dazed Pokémon has been separated from Jessie and James after a rough run-in with Team Galactic! After explaining the situation, Meowth and our heroes head out to Team Galactic's secret base to rescue Jessie and James, as well as Looker from the InternationalPolice.
As Team Galactic continues to put the pieces together to accomplish its evil plans, our heroes confront the mysterious Jupiter of Team Galactic. She informs them she is aware of their previous encounters with the three lake Pokémon Mesprit, Azelf, and Uxie. This news bewilders our heroes all the more. Meanwhile, the gang (along with Meowth) rescues Looker, who has been trapped in a cell with Jessie and James. Team Galactic gets away, leaving Looker and our heroes still wondering what the evil organization is up to.
While trying to unravel the mystery, Looker discovers an object left behind by Team Galactic that, upon examination, destroys every bit of data the International Police have collected on them
